keyword

Most keywords in C (or in any language for that matter) starts with a letter. But there are some keywords that starts with an underscore? They keywords are: _Alignas , _Alignof , _Atomic , _Bool , _Complex , _Generic , _Imaginary , _Noreturn , _Static_assert and _Thread_local . I find it amazingly strange. If it was a hidden global constant or internal function that's not really a part of the API, I would understand it. But these are keywords . I find it extra strange when C actually have a macros called bool and static_assert , and that their implementations is using the keywords. C developed

All, I'm building a site which will gather news stories from about 35 different RSS feeds, storing in an array. I'm using a foreach() loop to search the title and description to see if it contains one of about 40 keywords, using substr() for each article. If the search is successful, that article is stored in a DB, and ultimately will appear on the site. The script runs every 30 mins. Trouble is, it takes 1-3 mins depending on how many stories are returned. Not 'terrible' but on a shard hosting env, I can see this causing plenty of issues, especially as the site grows and more feeds/keywords

I'm executing the following query but it is giving syntax error. Because the keyword key is registered in SQL SELECT `id` AS key, `country_name` AS value FROM countries I also tried using brackets like this but it's not working: SELECT `id` AS [key], `country_name` AS value FROM countries How to deal with it? Use backtick(`) or Single Quote(') to give alias name of column in MySQL. Try this: SELECT `id` AS 'key', `country_name` AS value FROM countries; OR SELECT `id` AS `key`, `country_name` AS value FROM countries; key is mysql keyword so compiler suppose as mysql keyword, you should warp by

I've seen two approaches to building parsers in Scala. The first is to extends from RegexParsers and define your won lexical patterns. The issue I see with this is that I don't really understand how it deals with keyword ambiguities. For example, if my keyword match the same pattern as idents, then it processes the keywords as idents. To counter that, I've seen posts like this one that show how to use the StandardTokenParsers to specify keywords. But then, I don't understand how to specify the regexp patterns! Yes, StandardTokenParsers comes with "ident" but it doesn't come with the other ones

I have this where I get all my tournaments $tournaments = Tournament::all(); . Now I want to let the user filter these on the go in the view... I would like to have an <input> where the user enters a few characters and then the results filter on tournaments that have those characters in the name. I have found this* online but I dont know how to populate that $keyword . It would be best if the results filter after every character that is entered in the inputfield. If this is not possible, then make this a form that sends this $keyword to Controller and retrieves the new results on the same page

When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example: interface Garble { int zork(); } interface Gnarf extends Garble { /** * This is the same as calling {@link #zblah(0)} */ int zblah(); int zblah(int defaultZblah); } And then abstract class AbstractGarble implements Garble { @Override public final int zork() { ... } } abstract class AbstractGnarf extends AbstractGarble implements Gnarf { // Here I absolutely want to fix the default behaviour of zblah // No Gnarf shouldn
